Asthma is currently one of the most common chronic diseases worldwide, and it is estimated that 1 in 20 people worldwide, or about 300 million people, suffer from asthma. It is estimated that nearly 20 million people suffer from asthma in China. The global prevalence of asthma is increasing, especially in children. According to the Centers for Disease Prevention and Control, nearly 5 million children in the United States have been diagnosed with asthma. Despite aggressive research and preventive measures, asthma-related mortality among children in the United States increased by 78% between 1980 and 1993. The situation is just as bad in other countries: 1 in 4 children in Australia has been diagnosed with asthma; the prevalence of asthma in children in Israel has doubled to more than 11%; and the prevalence of asthma in children in Costa Rica, Panama, Brazil, Peru, and Uruguay is above 20%. Asthma is a global public health problem of great concern in recent years and is the most common chronic disease of childhood, and if not treated aggressively, about 1/3-1/2 of childhood asthma can be extended to adulthood. The prevalence of asthma in many countries now exceeds 10%, and the incidence of asthma in China has continued to grow in recent years, and the situation is not optimistic. The two surveys on the prevalence of asthma among children aged 0-14 years conducted in China in 1990 and 2000 showed that the prevalence of asthma among urban children nationwide increased from 0.91% to 1.50% in 10 years, with a 64.84% increase in prevalence. The prevalence of childhood asthma in Beijing has increased significantly, from 0.78% in 1990 to 2.05% in 2000, and there is a rising trend in all age groups. The results of the International Study of Asthma and Allergic Diseases in Children (ISAAC), a global multi-country study of children aged 13-14 years, show that the situation in China is as follows: the prevalence of asthma in Hong Kong is 10.1% and the average in the mainland is 2.0%. According to a survey of Beijing, Guangzhou, Shanghai and other cities, only 1% of asthma patients currently receive formal treatment. Within a year, 33% of patients had seen an emergency room, 16% had been hospitalized, 25% (20%) still had absenteeism (missing school), 42% had never had pulmonary function monitoring, and asthma control was unsatisfactory. At present, respiratory and asthma specialists and medical personnel from adult and pediatric departments around the world are working hard and painstakingly for the rehabilitation of asthma patients. Patients can be completely controlled and asthma patients can have a healthy and colorful life as long as they undergo long-term standardized treatment and management based on inhaled glucocorticoids through timely and correct diagnosis.
